Final answer:
The War Powers Resolution was meant to limit the President's ability to commit troops without congressional approval, but it effectively clarified their ability to act for sixty days without such approval. It requires notification to Congress within 48 hours and mandates withdrawal after sixty days without authorization or declaration of war.
Step-by-step explanation:
The War Powers Resolution impacted the power-sharing arrangement between Congress and the President by limiting the President's ability to commit troops without congressional approval. This legislation, enacted in 1973 over President Nixon's veto, was an attempt by Congress to reassert its war-making authority.
Despite the intention to strengthen congressional war powers, in practice, it clarified presidential authority to take military action without congressional approval for sixty days. Moreover, subsequent presidents have often used this as a window to initiate military actions unilaterally.
Presidents must notify Congress within forty-eight hours of deploying troops and are required to withdraw them after sixty days unless Congress authorizes the action or declares war. Although designed to restrict the president's unilateral military actions, the War Powers Resolution has been criticized for being ineffective at reining in presidential power, as many conflicts are resolved within the sixty-day timeframe, and presidents often interpret the requirements loosely.
